<P>The header <SAMP>&lt;complex&gt;</SAMP> is part of the Numerics library of the C++ Standard Library. It defines the class template <B><I><A HREF="complex.html">complex</A></I></B>, the specializations of the class template <B><I>complex</I></B> on types <SAMP>float</SAMP>, <SAMP>double</SAMP>, and <SAMP>long double</SAMP>, and a number of functions for representing and manipulating complex numbers.</P>
